Restoring/Re-installing

Alright, so here’s the deal. I recently had an issue with FastCGI and PHP on my Server 2003 ISS6…yes, it’s ancient…but hey I had to start somewhere. I uninstalled IIS, FastCGI, and PHP and began with the reinstall. Of course all of the custom files on my other sites work just as they did. But my WordPress site is only at about 1%.

I know I can restore from an older XML backup, however: not ideal. I am wondering if there’s a way to re-associate the index.php with the rest of the WordPress site.

More details:
When you go to the URL, the text loads, but no images, themes, nor the CSS loads. The only page that I can navigate to is the index.php. Any other file in the directory or sub-directory comes up with a 404 error.
